Rasmus Andersson would be a huge get and is still relatively young at 28. I don't see Calgary trading until the offseason though.
Noah Dobson? Problem is teams that are winning wont make a team changing trade and losing teams will probably want 1st round picks.
So we are stuck. Would love to see a hockey trade Top 6 forward for Top 4RHD.
I don't think Andersson and Dobson are good targets. Andersson doesn't have a long enough contract for our situation and he's not exactly the type of defenseman we need, although he might be good with Dahlin, but it's the same situation with Byram, where three defensemen want to play on the PP. Dobson is the same, too expensive (cost and contract), had problems with his play falling off this season.
Weegar would be perfect with Dahlin or even in the second pair, but I would rather consider him for the first pair. But full NMC, even though he is related to Rivet, I don’t think there are many chances. Although my philosophy is that you kick the tires on any player that suits you, even if he has NMC/NTC and maybe gets lucky somewhere, because don’t take money for asking.
UFA is unlikely, there will be few options, Ekblad? I doubt it, but I would try to get Kovacevic in UFA. But for me UFA is almost no, since few people will come to us, but still, again, they don’t take money for asking and you can overpay a little for the right player.
I'm looking for diamonds and potential options. For the second pair it's quite realistic, imo, and in theory even for the first, considering that we had Jokiharju there for many years.
Just example:
Dahlin - Weegar/Ekblad/Kovacevic/Pulock/Larsson
Power/Byram - Carlo/Whitecloud/Murphy/TVR/Kesselring/Chatfield/Helleson/Lamoureux/Korczak
Johnson - Clifton (in ideal TVR or Peeke)
Although if Dahlin was comfortable playing on RD and the coach was not against it, then this opens up more possibilities, since you can look for LD to play with Dahlin.
